Filed: 1967-11-10
Abstract: 1,251,326. Cooling beer. PORTER LAN. CASTRIAN Ltd. 4 Nov., 1968 [10 Nov., 1967], No. 51174/67. Heading F4H. Cooling jackets surrounding beer tanks in a cellar are selectively connectable to a chilled water circuit. The jackets are joined to the circuit by flow and return pipes which include valves allowing the selective connection. The arrangement of pipes may be such that water flows through the connected jackets in series or may be such that water flows through the connected jackets in parallel. Alternatively the pipes may be arranged to allow each jacket to be connected in series or in parallel with other jackets. In the latter case the jackets of those tanks which require cooling to their storage temperature may be connected in parallel while the jackets of those tanks merely requiring maintenance of their storage temperature may be connected in series.

Abstract: 1,259,051. Laminated battery separator. ESB Inc. 13 April, 1970, No. 17456/70. Head. ing B5N. [Also in Divisions C3 and H1] A laminated sheet for use as a battery separator comprises a semi-permeable membrane barrier material laminated to an absorbent sheet material consisting essentially of 10-30% by weight of a vinyl acetate-ethylene copolymer resin binder blended with a gelling agent. The semi-permeable layer preferably has a micropore size ranging from 5 to 50 Angstroms and is preferably made of "Cellophane" (Registered Trade Mark). Other suitable microporous materials for this layer are polyamide, polyester, polyolefin, polyvinyl chloride and acetate, and polyacrylate. The gelling agent may be selected from starch, flour, methyl and carboxymethyl cellulose, polyacrylamide resins, natural gums such as gum arabic, inorganic gelling agents such as silica gel and admixtures thereof. The two layers may be laminated using gum arabic as adhesive, or one or both layers may be treated with a solution to tackify the layer(s) after which they are laminated together. Alternatively the separator may be prepared by dissolving the vinyl acetate-ethylene copolymer in a solvent such as trichloroethylene and then adding the gelling agent such as wheat flour/ corn starch mixture. The viscous liquid formed after mixing is cast on a wetted "Cellophane" sheet by feeding it through an aperture or extrusion die. The laminated sheet is then heated to evaporate the solvent and water and is then calendered to a thickness of 4 to 18 mils using a 1 to 3 mil "Cellophane" sheet.

Abstract: 1301512 Matrix stores ELITEX-ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI 26 Feb 1970 [27 Feb 1969] 9331/70 Headings G4A and G4C [Also in Division D1] A magnetic matrix store for use with knitting machines comprises one or more matrices of magnetic elements, means to send pulses down a row and column of each simultaneously to change the magnetisation of the element at each intersection, means for applying an independent magnetic field to selected elements, and a read/erase wire associate with all the elements. The independent magnetic field is provided by permanent magnets beside the selected elements. A rotatably mounted disc 1 for a knitting machine has openings 2 and 3 which can be detected by a photo-cell 4 so as to send pulses along lines 5 and 8 for holes 2 and 3 respectively to synchronized pulse decoders 7, 10 controlling two matrices. Each matrix comprises magnetic cores 13, 26 having a rectangular hysteresis loop on wires 12, 14 having a diagonal read or erase wire 15, 27 interconnecting them which can be connected to an erasing circuit 18 or a reading amplifier 17. The permanent magnets 20, 21 (Fig. 3) are pins which can be wholly magnetic or part magnetic and part non-magnetic and which are distinguished by coloured heads 20, 22. Operation.-When a hole 3 passes the photocell 4 a pulse goes to decoder 10 and when a following hole 2 is detected the element at the intersection of lines 12a, 14a is energized and a pulse goes via the read line to amplifier 17. The next hole 2 energizes the element at the intersection of lines 14a, 12b &c. When the next hole 3 is sensed the element at the intersection of lines 12a, 14b is energized &c. and the elements on line 14a are erased. If a permanent magnetic is by any element, the element is not energized and the amplifier 17 receives no pulse. The read pulses goes through logic circuits to outputs 37, 39, 41 (Fig. 3) and thus different arrangements of the pins cause different outputs at 37, 39, 41 as indicated by the logic tables B, B<SP>1</SP> on Fig. 3.

Abstract: 1307431 Optical masking devices in photoelectric systems DEFENCE SECRETARY OF STATE FOR 16 June 1971 [19 June 1970] 29793/70 Heading G1A [Also in Divisions G2 and H4] Apparatus for detecting apparent movement of an object point or scene includes two pairs of masking patterns 1, 2, 3, 4, each mask pattern being formed of parallel alternately opaque and translucent bars, the mask patterns being mounted in parallel planes and in a fixed relationship to each other with all the bars parallel whereby parallel light 10, 11 incident on both pairs of masks which passes through the translucent bars of the first pair 1, 2 with maximum transmission will be substantially obstructed by the opaque bars of pattern 4 of the second pair. Each pair of patterns has an associated photo-sensitive element 6, the electrical outputs of which are connected to a differencing circuit 8. This then feeds a frequency measuring circuit 9, which produces an output analogue voltage proportional to the frequency. This may be used as a control signal for a velocity servo controlling the speed of a film in a camera to compensate for relative movement between image and the film. The outputs of elements 6, 7 are in antiphase and are signals having a frequency which depends on the velocity V of an object point across the plane of-the mask patterns, the distance d between the patterns of a pair the distance h to the object point and the spacing a between the bars. For use in aerial photography and to detect apparent movement in two mutually orthogonal directions two sets of such a masking device are used inclined at a predetermined angle, each having a frequency sensing circuit 9, 9', Fig. 2, the outputs of which are connected to a summing circuit 20 and a differencing circuit 21. Desirably the bisector D between the two sets is aligned with the direction of flight. A mask pattern 1 of the first pair may be formed on the same support as mask pattern 3 of the second pair; or both pairs may be formed on single integral support.

Abstract: 1307990 Variable geometry aircraft BRITISH AIRCRAFT CORP Ltd 21 May 1970 [27 May 1969] 26813/69 Headings B7G and B7W A variable sweep-back wing aircraft has a leading edge root member on each wing movable with respect to the wing so that when the wings are in a highly swept-back configuration the movable root members form a continuation of the wing leading edges, and when the wings are in an outspread configuration of reduced sweep-back the movable root members lie within the fuselage contour. Fig. 2 shows a portion of the port wing 3, which wing is arranged to swing about a pivot 5 mounted outboard of the fuselage 1 on a structure extending from the fuselage and smoothly covered by a fairing 6. The upper fuselage skin is cut away at 7 in the vicinity of the wing root leading edge. The leading edge root member comprises a rib 8 and an eyelid 9 both pivoted to the wing 3 about a vertical pivot 10. The rib 8 is also connected to the fuselage 1 by a pivot member 11 constrained to move bodily along a track 12 in the fuselage. Spring means 9A cause the eyelid 9 to remain in the position with respect to the rib 8 shown in Fig. 2 until positively urged into a different position. When the wing 3 is in a position of maximum sweep-back (Fig. 1, not shown) the inboard flank 18 of the wing remains just within the outboard flank 16 of the eyelid 9, and the inboard flank 17 of the eyelid 9 remains just within the outboard flank 19 of the rib 8. Also in this wing position, the inboard edge 30 of the rib 8 remains just within the line of the fuselage skin cut-away 7. When the wing 3 is swung forward about its pivot 5, the pivot 10 moves along an arc 20 and the rib 8 and eyelid 9 are both moved inwardly and forwardly, while remaining in the same position relative to one another, to an intermediate sweep-back position such as is shown in Fig. 2. The pivot 11 has moved forward along its track 12 to accommodate the arcuate movement of the pivot 10. As the wing 3 rotates further the eyelid 9 is urged away from its initial position with respect to the rib 8 by contact with the wing leading edge 4 and is carried into the interior of the rib 8. When the wing 3 has reached its position of minimum sweep, the leading edge 13 of the rib 8 lies along the fuselage contour 2 and the pivot 11 has moved rearwards along its track 12 (Fig. 3, not shown).
